Route Prediction Based Vehicular Mobility Management Scheme for VANET

Abstract

Since improvement of wireless communication, IP based mobility management protocols have been studied to provide seamless communication and mobility management. The vehicular ad hoc network (VANET) is one of mobility management protocols, especially providing seamless connection with inter/intra/inner vehicle communication. However, each vehicle moves fast that causes short-lived connections with Access Router (AR). Based on vehicles' characteristic, it is hard to provide the availability of IP services in VANET. The most critical issue of the design of scalable routing algorithm is to provide robustness of frequent path disruption caused by vehicles' mobility. In this paper, we pursue the characteristics of vehicles' mobility and analyze them. With the navigation information which is one of vehicles' mobility characteristics, we classify the mobility into intrahighway mobility and global mobility management. Furthermore, we propose mobility management scheme based on route prediction in VANET. Handoffs with intrahighway mobility are managed locally and transparency is provided to CHs, while global mobility is managed with Mobile IPv6. Finally, through the numerical analysis, we show that proposed mobility management protocol reduces handoff latency, signaling costs, and packet loss.

SmartHO: mobility pattern recognition assisted intelligent handoff in wireless overlay networks

“…Wanalertlak et al (2011) presents a behavior-based mobility prediction scheme in IEEE 802.11 networks, which captures short-term and periodic behavior of mobile users to provide next-cell predictions, and eliminates the incurred scanning overhead to reduce the handoff latency. Lee et al (2014) pursues the vehicles mobility characteristics, and classifies the mobility into intrahighway mobility managed locally and global mobility managed with MIPv6, and further proposes a mobility management scheme based on route prediction.…”

Secured Efficient Fast Handover Multihoming Based NEMO+ (SEFMNEMO+) for Vanets

“…Dae Won Lee [25] says that the characteristics of vehicles' mobility are analyzed with the navigation information; then it the mobility is classified into intra highway mobility and global mobility management. Furthermore, mobility management scheme based on route prediction in VANET are implemented for Handoffs with intra highway mobility.…”

An Adaptive Routing Protocol Based on QoS and Vehicular Density in Urban VANETs

“…ITS applications include cooperative traffic monitoring, traffic control, blind crossing, collision prevention, nearby information services, and real-time detour route computation [4], which have attracted attention from many car manufacturers, research institutes, and national transportation departments. Vehicle communications [5, 6] are the basic foundation of the above applications of VANETs.…”
